We look at the division of 883860 by 63 
The aim is to understand the frequency of 63 in 883860.

Step 1:
63 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 63

Advancing to step 2:
If we divide 88 by 63, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 63 from 88 to get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 63

On to step 3:
253 divided by 63 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 252 from 253 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 63

Let's proceed to step 4:
63 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 18 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 63

Let's proceed to step 5:
If we divide 186 by 63, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 1402.0
Deduct 126 from 186 and we're left with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 63

Step 6:
600 divided by 63 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 14029.0
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
330 divided by 63 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 14029.5
If we take 315 away from 330, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
63 goes into 150 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 14029.52
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
240 divided by 63 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 14029.523
Subtract 189 from 240 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
If we divide 510 by 63, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 14029.5238
The remainder is 6 after subtracting 504 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
63 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 14029.5238
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
If we divide 600 by 63, we get 9 and a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 14029.523809
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
The number 63 fits into 330 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 14029.5238095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 63 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14029.52380952
Subtracting 126 from 150 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 14029.52380952 with a remaining 2.4e-08.
